Parker SSD, part of the automation division of Parker Hannifin has introduced a new Profibus option for its 650V series ac drives. Designed to extend the functionality and performance of the 650V drives, the new Profibus options have been developed to allow the drives to be networked as decentralised peripherals in a wide range of variable speed motor control applications, including the control of fans, pumps and conveyors.
The 650 and 650V series ac drives help production and plant engineers minimise the time required for installing, configuring and operating drive units. The 650 and 650V are quick and easy to set up using standard program function blocks, with user selectable, pre-programmed applications that allow the inputs, outputs and drive parameters to be automatically set. Pre-programmed options include basic speed control, manual/auto control, preset speeds, raise/lower and PID control, while a choice of inputs and outputs plus a digital relay output and a motor thermistor input enable the drives to be controlled from either 0-10V or 4-20mA analogue setpoints, or from up to eight user-configurable digital settings.
The latest drives are extremely compact, being up to 40% smaller than many competing units, can be DIN rail or direct panel mounted and incorporate internal EMC filters as standard, to eliminate the cost of extra filters and additional earth connections.
The drives are available for use with single-phase 230V and three-phase 400V supplies, with power ratings of up to 2.2kW and 90kW constant torque (110kW fan rated) respectively. In addition, the drive units feature an overload protection of up to 150%, intelligent monitoring and diagnostics and an integral 6-button keypad, which can be supplied as a demountable unit for remote operation.
